If F-Droid won’t install an app or notify you about an update, the cause may be an Android install restriction, repository setup, version selection, or compatibility with an older Android release. Start with where the process stops: a disabled Install button, a missing app, a failed install, or an update that isn’t offered.
Install is disabled
Android can block app installation while another app draws over the screen. A screen filter, dimmer, or similar overlay could cover the real Install button with a fake one, so Android disables installation for security.
- Temporarily turn off apps that draw over other apps, such as screen filters or dimmers.
- Return to F-Droid and try installing again.
- If you cannot identify an overlay app, check Android’s system settings for controls related to displaying over other apps. Newer Android versions include system features for this, so a separate third-party overlay app may not be involved.
F-Droid describes this restriction in its app-management FAQ.
F-Droid is still loading its app catalogue
When F-Droid is opened for the first time, it downloads data from its default repository. The setup guide estimates that this can take 2 to 10 minutes, depending on connection speed. Wait for the download to finish before treating an empty or incomplete catalogue as an app-availability problem.

Android may also ask for permission to install apps from unknown sources. Grant that permission to F-Droid itself if you want it to install apps. If Android displays an error, note its exact wording; a specific message is more useful than guessing at a cause. See F-Droid’s installation guide.
An app is missing from the list
Check whether the repository that provides the app is present and enabled. In F-Droid, open Settings and inspect Repositories. If the app comes from a third-party repository, make sure that repository is enabled as well as the default one.

Adding a repository makes its apps available to browse; it does not install them automatically. F-Droid explains repository setup in its app-management FAQ.
F-Droid shows a newer version but does not offer it as an update
A newer version can exist without being the version recommended for your device. On an app’s page, open Versions and look for the release marked Suggested. F-Droid says this is the version closest to what the app developers publish in their source repository and intend users to install. A newer release may be a test or beta build, so it may not trigger an update notification.

If you want the highest compatible version, use Allow beta updates in the app-page menu. This opts into beta updates rather than changing which release F-Droid recommends by default. The client FAQ explains the distinction in its app-management guidance.
For apps supplied by third-party repositories, the maintainer may not have updated the version information yet. If the repository’s listing appears stale, check with its maintainer or report the outdated app data through F-Droid’s app-data tracker.

An older Android device cannot install or update
Before changing certificates or reinstalling the client, consult F-Droid’s live Android compatibility guidance. It lists the newest F-Droid release available for each Android range and notes that Android 6 and 7 can encounter certificate compatibility issues. The page describes installing the Let’s Encrypt ISRG Root X1 certificate and says the in-client mirroring system may help with certificate problems; follow its current instructions rather than relying on an old workaround.
An app update may also have dropped support for an older Android version. F-Droid recommends its Archive repository for finding older app versions that still support older releases of Android. Check the compatibility page for current details before adding or using it.

The problem persists
Collect the information that distinguishes a client problem from an app or repository problem:
- The exact Android error text, if one appears.
- Your device’s Android version and F-Droid client version.
- The app name and package name.
- Whether the app comes from F-Droid’s default repository or a third-party repository.
- Where the process stops: catalogue loading, app listing, download, Android’s install prompt, or update notification.
- Whether a screen-overlay app is active, if the Install button is disabled.
For a problem with the F-Droid client itself, use the client issue tracker. For missing or outdated repository content, use the app-data issue tracker.
